Unfortunately, it is extremely limited and usually not worth the hassle. My suggestion would be to do something like this: have a page which shows a login form. The form posts back to itself (the same page). When there is no input, the script displays a blank login form. If there is input, the script attempts to validate the login data. If the data validates, the script somehow calls the next page (sends a redirect header, or include()s the code, or instantiates that page's class, etc...). If not, it redisplays the form, perhaps with some added information about what went wrong. It's important to note that nothing is ever sent to the browser until all needed information is known...that way, you always have the option to alter the output, or send a redirect header, or whatever.
